Definitions
- the present invention relates to a spreading device for spreading an asphalt mixture on a construction surface, and more particularly to a technique for improving the transport efficiency of the spreading device and the spreading efficiency of a pavement material.
- multi-layer leveling device In asphalt pavement, in order to improve drainage and noise reduction and reduce material costs, construction may be performed in which multiple pavement materials are spread in layers.
- the upper layer When the upper layer is spread with a thin layer in such construction, if the aggregate protruding from the surface of the upper layer is dragged by the screed, the upper layer surface will be damaged. It is necessary to spread the upper layer on the top.
- the upper layer when the upper layer is spread with a thin layer, there is a problem that the temperature drops drastically and it is difficult to obtain a density after compaction. Therefore, in order to spread the upper layer immediately after the lower layer is spread, a leveling device (hereinafter, referred to as “multi-layer leveling device”) that can simultaneously construct multiple layers of pavement is used. .
- the multi-layer leveling equipment is used less frequently than the single-layer leveling equipment, there was a problem that it was difficult to collect the funds required for the introduction of the equipment. For this reason, as described in JP-T-200-520-4636, the auxiliary equipment for multi-layer leveling can be attached to and detached from the leveling base for single-layer leveling. A technology has been proposed to reduce the cost by attaching it to a general purpose.
- the asphalt spreader when transporting the asphalt spreader to the construction site, it is desirable to transport the asphalt spreader with the attached equipment attached to the spreader base, considering the transfer efficiency.
- the height of the asphalt spreader may interfere with the lower surface of a building such as a bridge during transportation because the height of the asphalt spreader is higher when the accessory is attached to the spreader. For this reason, even if the transport efficiency is slightly reduced, it is necessary to transport the spreader and the accessory separately.
- An object of the present invention is to provide an asphalt leveling apparatus that improves the transport efficiency of the leveling apparatus and the leveling efficiency of paving materials. .
- an auxiliary device for single-layer spread or multiple-layer spread is used for a spread base apparatus having a base conveyer for conveying and supplying a pavement material onto a construction surface. Is selectively removable.
- Ancillary equipment for single-layer leveling consists of a base hopper unit that stores pavement material and supplies it to the base conveyer, and a base screw unit that spreads paving material conveyed and supplied on the construction surface by the base conveyer. And.
- the auxiliary equipment for multi-layer leveling is a lower-layer hopper unit that stores the lower-layer pavement material and supplies it to the base conveyer, and a lower-layer pavement material that is conveyed and supplied to the construction surface by the base conveyer.
- the upper hopper has a pair of left and right buckets each having a substantially trapezoidal cross section, which are supported by a support shaft extending in the front-rear direction of the vehicle so as to be openable and closable, and an upper portion of the bucket is foldable.
- a single-layer spreader or a multi-layer spreader is configured by selectively attaching an auxiliary device for a single-layer spread or a multi-layer spread to the spread-base device.
- the upper layer is spread immediately after the lower layer is spread. For this reason, the upper layer is spread on the lower layer in a hot and uncured state, and the engagement of aggregates is improved compared to using multiple single-layer spreaders to spread multiple layers individually. Thus, the interlayer bonding property is improved. Then, when the upper layer is pressed and spread, the lower layer is pressed again, so that the compaction property is good and as a result, the flatness is also improved. Furthermore, even when the upper layer pavement material is spread in a thin layer, the upper layer aggregate is pushed into the lower layer when the upper layer is pressed, so that the aggregate does not protrude from the upper layer surface, and the aggregate is dragged. The roughening of the finished surface due to the surface is prevented, and a high-quality pavement surface can be formed.
- the bottom of the bucket is inclined by closing the packet, so that the pavement material remaining on the bucket bottom surface can be sent to the discharge groove. By doing so, the pavement material can be supplied smoothly and the leveling efficiency can be improved.
- the upper part of the rear wall of the upper hopper be extended to be higher than other side walls and be foldable. According to this configuration, if the rear wall is unfolded when the upper layer pavement material is injected from the front of the asphalt spread device, the rear wall becomes a guide for work and a sense of distance can be grasped, so that the work can be easily performed. it can. On the other hand, when transporting the asphalt spreader, the rear wall of the upper hopper must be folded. As a result, the overall height of the asphalt spreading device is reduced, and the possibility that the rear wall interferes with the lower surface of a building such as a bridge is reduced.
- the lower layer screed unit is a lower layer spreader that spreads the lower layer pavement material conveyed and supplied on the construction surface to the pavement width, and a lower layer spreader that presses and spreads the lower layer pavement material. It is desirable that the upper layer pavement material conveyed and supplied on the lower layer pavement material be spread over the pavement width, and the upper layer spreader be integrally provided. According to such a configuration, while the overall length of the asphalt spreading device is shortened and the weight balance before and after is improved, the lower layer pavement material and the upper layer pavement material can be spread over the pavement width, so that the final pavement thickness can be reduced. It can be managed with high precision. In addition, since the lower layer spreader, the lower layer screed and the upper layer spreader are integrally provided, it is possible to easily attach / detach an accessory device for multiple layers.
- the lower layer screed unit has a configuration in which a lower layer screed on which a lower layer pavement material is spread is suspended by a hydraulic jack. According to such a configuration, the overall width and the overall length of the asphalt spreading device are shortened, and the transportation can be facilitated.
- the difference in the height of the leveling surface between the upper screed unit and the lower screed unit is detected, and the leveling height of the lower layer pavement material by the lower screed unit is set so as to be a predetermined value. It is desirable to adjust. According to such a configuration, the spread thickness of the upper layer can be controlled with high accuracy, and the amount of expensive upper layer paving material used can be minimized. Therefore, construction costs can be reduced while maintaining high pavement quality.
